Safety Precautions

Safety Precautions

Before performing operations, read through this manual and follow all the precautions to prevent accidents. The safety precautions provided in this document do not cover all the safety precautions. Huawei shall not be liable for any consequence caused by the violation of the safety operation regulations and design, production, and usage standards.


Huawei shall not be liable for any consequence caused by any of the following events.

  • Transportation
  • The storage conditions do not meet the requirements specified in this document.
  • Violate the operation instructions and safety precautions in this document for installation, cable connecting, and maintenance.
  • Operation in extreme environments which are not covered in this document
  • Unauthorized modifications to the product or software code
  • Installation or use in environments which are not specified in related international standards

Personnel Requirements

Only certified electricians are allowed to install and operate the SUN2000.

  • Operation personnel should receive professional training.
  • Operation personnel should read through this document and follow all the precautions.
  • Operation personnel should be familiar with the safety specifications about the electrical system.
  • Operation personnel should understand the composition and working principles of the grid-tied PV power system and local regulations.

Protect Labels

  • Do not tamper with any warning labels on the inverter enclosure because these labels contain important information about safe operation.
  • Do not tamper with the nameplate on the inverter enclosure because it contains important product information.


  • Ensure that the inverter is not connected to a power supply and is not powered on before starting installation.
  • Ensure that there are no objects within 200 mm (7.87 in.), 300 mm (11.81 in.), 500 mm (19.69 in.), 600 mm (23.62 in.), and 1000 mm (39.37 in.) of the left, right, top, bottom, and front of the inverter, respectively. This is to allow sufficient space for installation and heat dissipation. For ease of installation, ensure that the inverter bottom is at most 730 mm (28.74 in.) above the floor. If you have any questions about the distance, consult the local technical support engineers.
  • Ensure that the inverter is installed in a well-ventilated environment.
  • Ensure that the inverter heat sinks are free from blockage.
  • Open the maintenance compartment door of the chassis before connecting cables. Do not perform any operation on other components inside the chassis except connecting the PE cable, AC power cables and communications cables.

Cable Connections

Before connecting cables, ensure that the inverter is secured in position and not damaged in any way. Otherwise, electric shocks or fire may occur.

  • Ensure that all electrical connections comply with local electrical standards.
  • Obtain approval from the local utility company before using the inverter to generate electricity in grid-tied mode.
  • Ensure that the cables used in a grid-tied PV system are properly connected and insulated, meet all specification requirements.


High voltages may cause electric shocks result in serious injury, death or serious property damage from inverter in operation. Strictly comply with the safety precautions in this document and associated documents when operating the inverter.

  • Do not touch an energized inverter because the heat sink may be over 60ºC (140°F).
  • Follow local laws and regulations when operating the equipment.

Maintenance and Replacement

High voltages may cause electric shocks result in serious injury, death or serious property damage from inverter in operation. Prior to maintenance, power off the inverter and strictly comply with the safety precautions in this document and associated documents to operate the inverter.

  • Maintain the inverter with sufficient knowledge of this document and proper tools and testing equipment.
  • Before performing maintenance tasks, power off the inverter and wait at least 5 minutes.
  • Place temporary warning signs or erect fences to prevent unauthorized access to the maintenance site.
  • Rectify any faults that may compromise the inverter security performance before powering on the inverter again.
  • Observe ESD precautions during the maintenance.
  • For personal safety, wear insulation gloves and protective shoes.
